One method of supporting a machine ofths'character upon its carriage has been to provide supports at three positions, namely, at one position midway between the sides in the region of the haula e endL .of the machine (hereinafter referre Vto as the tail of the machine) about an approximately horizontal longitudinal axis, Ythe support at this position being incapable of vertical or other adjustment, except vertically by disconnection and reconnection of the support, and at two other positions in the region of the cutter member' end of the machine (hereinafter referred to as the head of the machine) by means of screwed standards, one on each side, each standard being pivotally connected to the carriage about a horizontal" longitudinal axis and so iconstructed that by vertical adjustment the body of the machine could be tilted on its carriage by being partly turned about its longitudinal axis, or raised or'loWe-red at its head, or have a combination ot' these adjustments imparted to it, as required; l

ln the known type of mounting adopted, the axial support at the tail of the machine was such as would permit the 'body to turn about its longitudinal axis, and to seine exs tent inove endvvise and angulariy about the position of support, and-the connections of the screwed standards wit the carriage and 'the body at the head of the machine were made slack in order to the freedom which the altered positions of the body of the machine upon :its carriage due to ad? justinents required. lin consequence of this slackness, the method adopted did not prof" nde @rigid Supreme? the haer' et the Tiflis invention refers tomining machines, and the like, having a cutter member at I Specicationof Letters Patent,

yApplication tiled May 12, 1914. Serial No, sagl) I head, of the bar, disk, .chain or the like una hereinafter referred to V.as lcoal .cuttingnia chinos, of the` type wherein the body of the machine is mounted upon a carriage and supported at three positions corresponding to the positions defined with reference to the system ,of support explained above, and

.the objects of the invention are to provide improved means for rigidly supporting the body @if .the alahne 11p-0n its Carriage which will give the necessary -freedom to enable the required adjustments ,to he effected Without slackness inthe connections,

and, if desired, to obtain an, additional or .l

improved method of adjustment by providing a' screw support at its tail.

In the method of support to which this invention refers` in consequence of adjustments at the tail or head of the machine which cause the longitudinal axis of the body of the machine \to be altered relatively to its carriage, there occur alterations of the distance in the projection of the body on the carriage, or, lin other Words. in the 'distance apart of the actual longitudinal positions at which the body is supported above the carriage. in the same way; in consequence of adiustments which cause the body to be tilted about its longitudinal axis, there occur alterations of the distance apart oi" the actual transverse positions at which the body is supported above the carriage, and the improved means according to this invention are devised to give the freedom required to permit the alterations of these distances Which occur Without resorting to slackness in the parts: and the additional or improved method of adjustment according to this invention is obtained by uroviding a screw support whereby, with the svsteni of support in question. the tail .of the machine may be raised or lowered.

Some esenciales of construction according to' this invention will now be described with reference te te@ aeomrainvine drawings, in

Figura@ is Side sctona elevation Showing a supaert a .maatian of vhih is shown in side sectional elevation atFig. 21 and in Satiaeal plan at Fia .3, and 0f llvhich. afurther mediiicationis shown in seetiohalside elevation at @and in end elevation at Fig'. 5eachadanted ,for appli;

' port for the tail end of the body A of a machine, the transverse tie B2, at a position midway between the skids B B1, is provided witha'longitu'dinal guide B4 in which a spherical socket C is mounted and adapted to slide, the guide B2 being formed so as to prevent the socket C from rising or jmoving transversely. In the socket C, the ball foot of a screwed standard D is mounted, the standard D being'bored and screwed internally to receive a screwed elevating spindle E. Fixed to and extending from the tail of the body A is a bracket having a guide F into which the standard D fits, the head of the guide F forming an abutment`which rests upon a collar Ef of the spindle E.'

An extension of the'. spindle E passes through a more in the head of the guide F and is formed at its top to receive .a key, Spanner. or the like, for rotating the elevat- I ing spindle E. An additional collar Ez V(iti may be fitted above the head of the guide F to prevent the elevating spindle from moving endwise in the guide F. In this form of construction freedom to permit changes in the actual longitudinal position of support is obtained'by the 'socket C beingfallowed to slide longitudinally inl .the guide B4. y

In the construction of support show n'at Figs. 2 and 3, 4the socket C'is rigidly xed to the transverse tie B2, and the standard D is formedwith an upper part having flat and parallel sides D1 D2, which fit between the sides of the guide F which are correspondingly formed. The front and vback faces D2 D2, of the upper part of the standard D are circular and fit between the back and front interior faces of the guide F which are flat and parallel. Each of the contacts of these faces is consequently4 about a straight line. The top of the elevating "spindle E extends througha longitudinal slot formedin the head of the guide F, and the head of the guide is curved and the contiguous faces of the collars El E2 are correspondingly shaped. In this form of construction free-y dom topermit changes in the actual longitudinal position of 'support is obtained by the angular movements which the standard D is free to make about the transverse axes of the socket C and the circular front andback faces D2 D2of the upper part of the standard.

In the construction/of support shown at Figs. 4 and v5, D designates a standard which is rigidly fixed to and extends upwardly from the skids B B.1 of the carriage, preferably, asshown, at anl angle inclined toward the head of` the machine. -The base of the standard D is constructed so as to form a transverse'tie B2. The standard D is formed to serve as guides for a slipper G which is adapted to be raised or lowered therein by means of a screwed elevating spindle. E

which passes through a correspondingly screwed head D3 of the standard. Within the slipper G a sleeve H is pivotally supported on transverse trunnions. vFixed to and extending from the tail of the body A of the machine is an axle J which fits and' is free to slide longitudinally in the sleeve H, and provides freedom which permits changes in the actual longitudinal position 'of the support of the body of the machine upon its carriage.

. An exampleof the construction of sup ports for use at the hea'd of a machine will now be described with reference to Figs. 6 and 7. n constructioneach of the supports shown is substantially the same as'that described and shown with reference to Fig. l, with the exception that the socket C1 of the support on the right hand side of the body A is rigidly xedto the ltransverse tie B3 close to the skid B2, and, as shown at Fig. 7, the socket C2 of the support 'on the left hand side of-the body A is mounted in a transverse guide B5 fixed on the transverse tie B3 in which guide the socket C2 is mounted and adapted to slide, the guide `B5 being formed so as to prevent the socket C2 from rising or moving longitudinally. In Fig. o,

the socket C2 is shown with the guide B5 re moved, and Fig. 7 is a side view showmg the complete, guide B5 and associated socket C2. In this form of construction, freedom to permit changes in the actual transverse position of support is obtained by the socket C2 being allowed to slide transversely in the guide B5.

In supports constructed as shown at Figs.

1 and 6, the standard D, if cylindrical, may.

be prevented from rotating in the guide F, as shown at Fig. 6, by means of a stud I arranged to engage witha slot ft in the side of the standard D.

Referring to Fig. 8, which shows a modified construction of supports for use at the head of a machine, upright standards K K1 are provided, each rigidly fixed at its foot lto the carriage and fitted with elevating screws E E. Upon the screw E of the standard K isa sleeve L screwed internally to receive the elevating screw E, andextending transversely from the sleeve Lis a spherical shoulder M which fits within a corresponding socket N fixed to the side of the bodyl A of the machine. The screw i `re erence to Fig. l,

-v to Figs. 4 and 5, may

' and 5 is provided, the axle `versely a shoulder L2 ever, maybe obtained at the si adelante E of the standard K1 is providedfwith a.' sleeve L1 from which there extends trans` which fits into a slot formed in a. ball M1 which Vtits within a spherical socket N1 'body A. of the machine. In this form of construction freedom to permit changes in vthe actual transverse position `of support is obtained by the shoulder L2 being allowed to slide transversely in the ball M1.

The body of a machine provided with a su port at its tail. such as is described with or to Figs. 2 and 3, or be mounted at its head upon supports such as are described with'rei'- erence to lligs. 6 and 7,'or to l1` ig. 8, and with these means freedom to permit changes in the actual longitudinal position or'. support is obtained at the support machine. Thisy longitudinal feedom, howhead of the machine, for example,- in Figs. 6 and`8 the feet of the supports may be free to slide longitudinally, for example, the tie B3 on which they are mounted 'may be made free to slide longitudinally. lt longitudinal freedom is'. provided at the head it is then not required at the tail of Ythe machine, and if .a support such as is shown at F ig. yl is provided,'the socket C is then rigidly fixed to the transverse tie B2, or it a support such as is shown at Figs. 4 .l is fixed so as to lie prevented from sliding eiidwise in the sleeve H.

By this invention a system of support is provided whereby the body A of the machine ycan be tilted about its longitudinal 'axis and is capable of being adjusted vertically to meet the required conditions. V ertical adjustments oi the head of the body, and consequently oi the cutterinember, may be made by adjustments at the tail oi' the machine, the body then moving about the supports at the head oi the machine as a 'fulcrum, or the vertical adjustments maybe made at the head supports, the body then movingl about the support at the tail as a fiilcruin, or adjustments may be ricade at the tail support and also at the head supports. Tilting adjustments of the body of the machine are made by adjustments at one or both ofthe supports at the head of the machine.

Machines mounted according to this invention may be provided with a support at the tail of the machine which is incapable of vertical adjustment, in which case the adjustments of the body are rall effected at the `head supportso l claim:
